How to Effectively Replace " with " in Python Files

Working with strings in Python, especially when dealing with escape characters, can be a bit tricky. A common task developers encounter is needing to replace certain sequences in text files, such as changing " to ". If you're facing challenges with this in your code, you're not alone! Let’s break down the problem and the solution step by step.

Understanding the Problem

In your original code, you had the intention to read a file and replace occurrences of " with ". However, the current implementation is not functioning as expected. You observed that the code runs without errors, but the characters are not being replaced correctly.

What's the Issue?

Incorrect Escape Sequence: You used ", which is not the correct form of the string you want to replace.

The Correct Approach

Let’s solve the issue and get your code working perfectly to replace " with ".

Step 1: Read Your File
